Keywords: | Cyclic voltammetry;Electron paramagnetic resonance (EPR) spectroelectrochemistry;Heterocyclic push-pull alkenes;Semiempirical MO-calculations;UV-vis spectroelectrochemistry | Issue Date: | 1-Sep-2012 | Journal: | Electrochimica Acta | Abstract: | Electrochemical and spectroelectrochemical study of the reduction of (Z)-2-(5-ethoxycarbonylmethyl-N-methyl-4-oxothiazolidin-2-ylidene) -1-phenylethanone in an aprotic solvent (dimethylsulfoxide (DMSO)) has been presented. The results indicate an ECCEE reaction sequence, whereby the chemical step is a protonation of the anion radical electrogenerated in the first electron transfer step by the enol tautomer of the substrate. The gas phase and solvent dependent PM3 semiempirical modelling allowed further rationalization of experimental data pertinent to the suggested electrochemical redox mechanism and the reactivity of the intermediate species involved. © 2012 Elsevier Ltd. |
